Rather than relying on network firewalls, Software Defined Perimeter (SDP) focuses on dynamically protecting resources by creating secure connections between assets and the users. Needless to say, in today’s world of remote work, having such an architectural solution can ensure safety for both the company and the users. 

Thankfully, today’s SDP solutions are quite versatile, and thanks to a growing supply in the market, they have also become fairly cost-effective for most businesses. While numerous SDP offerings adopt a zero-trust methodology by concealing services, apps, networks, and devices until validation of requests, they also contribute to creating tailored network architectures that enhance the effectiveness of zero-trust security methods. To be considered part of the SDP category, a product needs to possess dynamic, detailed network segmentation capabilities.

So, if you want to start building your zero-trust architecture with an SDP solution, here are some of the best providers worth considering.

Twingate focuses on providing companies with the tools to help them create a modern zero-trust network without making any changes to the underlying infrastructure. It is a cloud-based service that delegates authentication to a third-party identity provider. A notable aspect of Twingate SDP is its approach to user access authorization. It consistently requires a second or even third level of verification, depending on how critical the access decision is. This means that no single element has the authority to permit traffic flow to another component or resource within your remote networks, ensuring a more secure and controlled access process.

With Twingate you can apply two-factor authentication (2FA) for anything, add RDP, SSH, and similar services, and also integrate your SDP with identity providers (like Google Workspace, Okta, and OneLogin) to smoothly onboard and off-board users.

What’s more, you can use Twingate completely free of charge for up to 5 users, and if you want more, you can try out any of their plans with a 14-day trial before making a decisive decision.

The cheapest plan costs $5.00 per month and supports up to 100 users and up to 20 remote networks in total, which makes it best suited for small teams.

Pick up an SDP and get started with zero-trust security

To sum it all up, SDP solutions properly fill gaps between VPNs and firewalls, providing security for data, across all end-points. Thanks to its zero-trust paradigm, no resources will be released until users have been verified. Solutions that provide MFA and biometrics give an additional layer of protection, though more work for the end user. Enhanced network security is the ultimate outcome, as malevolent actors are unable to detect any network resources. 

The significance of SDP technologies in today's network frameworks is paramount, especially given their flexibility and scalability in a time marked by increasing remote work and cloud-centric business operations. If you’re looking to get started, our suggestion would be to test out the above-mentioned solutions, especially ones with a free trial/demo, or money-back guarantee.
